Assets "Relate" to the Business if they are used or intended to be used by the Sellers exclusively or predominantly (i.e. are used for the Business at a level of more than 90% of their total utilisation) in connection with the operation of the Business including the assets specified in the Schedules under Sections 5 to 11.

8. ORIGINAL HEREDITARY BUILDING RIGHT; PERMITS AND AUTHORISATIONS

8.1 The assets of the Business include certain parts of the Original Hereditary Building Right in relation to the Schkopau Rubber Facility. The creation, sale and transfer of such parts of the Original Hereditary Building Right is governed by a separate agreement which shall be executed by Seller 2 and the Purchaser 2 substantially in the form attached hereto as Schedule 8.1 ("Rubber Hereditary Building Right Agreement"). The new (partial) hereditary building right that is to be created and transferred to the Purchaser 2 pursuant to the Rubber Hereditary Building Right Agreement is herein referred to as the "Rubber Hereditary Building Right". The Purchaser 2 hereby undertakes to acquire the Rubber Hereditary Building Right based on the Rubber Hereditary Building Right Agreement in accordance with the foregoing sentence in rem (dinglich) as of the Closing Date or as soon as possible thereafter. In the event of a conflict between the provisions of this Agreement and of the Rubber Hereditary Building Right Agreement, the provisions of the Rubber Hereditary Building Right Agreement shall prevail.

In the event that the current buildings and facilities are legally considered non-genuine or fictitious components (Scheinbestandteile) of the respective property / hereditary building right and are in the ownership of Seller 2, Seller 2 hereby transfers – in addition to the Rubber Hereditary Building Right Agreement – such ownership to the Purchaser 2 with effect as of Closing Date free and clear from any encumbrances and lien.

Seller 2 and the Purchaser 2 undertake to enter into the Rubber Hereditary Building Right Agreement on the Signing Date or as promptly as practicable following the Signing Date. They acknowledge that Dow Olefinverbund GmbH must consent to the partition (Teilung) of the Original Hereditary Building Right as well as the sale and transfer of the Rubber Hereditary Building Right. The required consent from Dow Olefinverbund GmbH will be issued by approving the Rubber Hereditary Building Right Agreement (Schedule 8.1) after Signing. Furthermore Seller 2 and the Purchaser 2 acknowledge that the registration of certain contractually granted extensions of the Original Hereditary Building Right is still pending due to outstanding consents of beneficiaries of rights registered in section II of the land register.

Notwithstanding the foregoing and Sections 19.1.1(d) and 19.1.2, each Party shall seek to obtain (i) the consent of beneficiaries of rights registered in section II of the land register in relation to the pending registration of contractually agreed extensions of the Original Hereditary Building Right, and (ii) the consent of Dow Olefinverbund GmbH regarding the creation, sale and transfer of the Rubber Hereditary Building Right as contemplated in the previous paragraph prior to completion of the Transaction.

8.2 Seller 2 holds the permits, licenses, approvals, exemptions, authorisations and other public law authorizations and decisions which are listed in Schedule 8.2 ("Permits"). To the extent permitted by applicable law, they will transfer automatically to the Purchaser 2 together with the corresponding buildings and installations. The parties clarify that the permits under Radiation Protection Law (Strahlenschutzrecht) do not transfer automatically but must be newly applied for by the Purchaser 2. For the avoidance of doubt, the Parties clarify that permits, authorizations, approvals and the like which do not relate to the Schkopau Rubber Facility as such but to the operation of the Schkopau site as a whole ("Business Site Services Permits"), e.g. permits for the

20

tank farm and/or waste water treatment/discharge, are held by Dow Olefinverbund GmbH as the operator of the Schkopau site and provider of related site services.

9. EXCLUDED ASSETS AND EXCLUDED LIABILITIES

9.1 The Purchasers expressly understand and agree that all rights, titles and interests of the Sellers in and to all properties and assets of every kind and description, whether tangible or intangible and wherever located which are not Sold Assets, including the following assets and properties of the Sellers ("Excluded Assets") shall not be sold, transferred or assigned to the Purchasers pursuant to this Agreement:

9.1.4 all rights of the Sellers arising under this Agreement or the transactions contemplated thereby;

9.1.6 any Mixed Contract (other than to the extent relating to the operation and conduct of the Business);

9.1.7 insurance policies taken out by the Sellers or any of their Affiliates, whether or not relating to the Business, and all claims, credits or rights thereunder; and

9.2 The Purchasers assume obligations and liabilities from the Sellers only if and to the extent they occur in connection with the Sold Assets or to the extent otherwise regulated herein, in particular as regards Environmental Liabilities as well as liabilities regarding Transferred Employees. Sellers expressly understand and agree that the following obligations and liabilities of the Sellers shall not be transferred or assigned to or assumed by the Purchasers pursuant to this Agreement:

9.2.1 obligations and liabilities created or incurred in connection with shares, fixed assets (Anlagevermögen), current assets (Umlaufvermögen), other movable property, contracts, rights, intellectual property and liabilities which are not Sold Assets;

9.2.2 obligations and liabilities to the extent they do not exclusively occur in connection with the Sold Assets;

21

9.2.3 all of the Sellers' account payables in compliance with Section 10.5, i.e. unless sold and transferred under this Agreement and reflected in the Binding Intangible Working Capital Accounts;

9.2.4 obligations and liabilities resulting from loans or other forms of financing or from guarantees provided or any other financial obligations and liabilities; and

9.2.5 any short or long-term liability position (long-term debt, other non-current liabilities, accounts payable and accrued expenses and other liabilities), except for such pension-related liabilities that are transferred pursuant to Section 12.12;

provided that the above shall not apply if an obligation or liability is transferred to the Purchasers under this Agreement, if the Purchasers are obliged to indemnify the Sellers from the respective obligation or liability or if pursuant to this Agreement, the risk has been allocated to the Purchasers pursuant to the terms of this Agreement (e.g. as regards Environmental Liabilities due to the absence of a further reaching indemnity than the one set out herein or in relation to liabilities transferring with the employees).

10. TRANSFERRED CONTRACTS

10.1 Rights and obligations transferred

10.1.1 Seller 2, Seller 3, Seller 4 as well as Seller 5 and the Purchaser 2 hereby undertake with effect as of the Closing Date to transfer the following contracts and purchase orders ("Transferred Contracts") to the Purchaser 2 – subject to any counterparty's required consent and further subject to Sections 10.2 and 10.3, with debt-releasing effect (schuldbefreiende Vertragsübernahme) – , excluding, for the avoidance of doubt, the account receivables in accordance with Sections 9.1.2 and 10.5 and the account payables in accordance with Sections 9.2.1 and 10.5:

(a) the contracts with suppliers, service providers, contract manufacturers, customers, tenants or landlords and other third parties, as well as the joint development agreement and commercial cooperation agreement with TRS, especially those contracts listed in Schedule 10.1.1(a), including those entered into following the Signing Date, in accordance with Section 20.4, until the Closing Date, in each case which Relate to the Business,

(b) the Mixed Contracts as set forth in Schedule 10.1.1(b) or as entered into following the Signing Date, in accordance with Section 20.4, until the Closing Date (but only the part of the Mixed Contracts that Relates to the Business).

22

The Transferred Contracts do not include:

(a) any agreements relating to the acquisition, sale or encumbrance of real properties or rights equivalent to real property (grundstücksgleiche Rechte);

(b) any agreements relating to the acquisition, or sale of shares of or interests in other companies or partnerships, except for the sale and transfer of Seller 4's participation in TRS pursuant to Section 6;

(c) any loan or other credit agreements entered into by the Sellers as lender or borrower (except for customary payment deferrals agreed in the ordinary course of business) as well as factoring agreements; and

(d) any guarantees, payment guarantees (Bürgschaften), assumptions of debt (Schuldübernahmen), collateral promises (Schuldbeitritte), comfort letters or similar legal instruments issued by the Sellers.

10.1.2 The Transferred Contracts, with the exception of the four lease agreements listed in Schedule 10.1.1(a) which shall be transferred subject to and in accordance with Schedule 8.1, shall be transferred subject to and with effect as of Closing and, subject to Sections 10.2 through 10.5, the Purchaser 2 agrees to replace the relevant Seller as a party to the Transferred Contracts and to observe and perform all such obligations of the relevant Seller in substitution of the relevant Seller with effect as of the Closing Date. To the extent that none of the Sellers is a party to the relevant contract listed in Schedule 10.1.1(a) (e.g. as regards the contracts entered into by Trinseo (Hong Kong) Ltd.), Seller 1 procures to instruct its relevant Affiliate to adhere to the transfer mechanism set out in this Section 10.1.

10.2 Consents for the transfer of the Transferred Contracts

Unless set out otherwise in Section 10.4, following execution of this Agreement and until the Closing Date, each of the relevant Sellers and the Purchaser 2 shall use its best efforts to obtain any counterparty's consent required under any Transferred Contract and to take such other actions as may be necessary to fully effect the transfer of the Transferred Contracts to the Purchaser 2, provided, however, that the relevant Seller and the Purchaser 2 shall not be required to make any payments or grant any other benefits to the respective counterparty in order to obtain such consent. To this effect, the relevant Seller shall notify the counterparties of the Transferred Contracts by a notice substantially in accordance with Schedule 10.2. In the event that counterparty's consent is withheld, delayed or conditioned by the Closing Date, Section 10.3 shall apply to such Transferred Contract.

10.3 Lack of Counterparty's Consent

10.3.1 In the event that any counterparty withholds, delays or conditions any consent that is required for the transfer of a Transferred Contract and release of the relevant Seller, and to the extent legally permitted, the relevant Seller and the Purchaser 2 shall economically treat each other,

23

and accept to be treated, as if the transfer had been effected as of the Closing Date as set forth herein and no delay or withholding of a consent shall entitle any Party to withdraw from or delay the Closing. Accordingly, (i) the relevant Seller shall, as from the Closing Date, continue to perform its obligations under the respective non-transferred agreement as towards such non-consenting counterparty in its own name but for the account and risk, at the cost, and pursuant to the directions (as long as such directions do not violate the respective agreement or applicable law) of the Purchaser 2, (ii) the Purchaser 2, as from the Closing Date, shall provide the relevant Seller (at such point of time as reasonably required under the respective Transferred Contract) with any goods, services or support necessary to enable the relevant Seller to perform such agreement, and (iii) all the rights of the relevant Seller under such agreement shall be assigned to the Purchaser 2 and all liabilities and obligations of the relevant Seller shall be assumed by the Purchaser 2 at no additional cost to the Purchaser 2, in each case as from the Closing Date unless provided otherwise in Section 10.5 which shall apply accordingly.

10.3.2 If such transfer is not permitted, however, the relevant Seller shall promptly pass on to the Purchaser 2 any monies or other benefits received under such non-transferred agreement relating to the period and activities from the Closing Date (including the Closing Date). For the avoidance of doubt, the Purchaser 2 shall promptly pass on to the relevant Seller any monies or other benefits received under such non-transferred agreement relating to the period and activities prior to the Closing Date. Section 10.5 shall apply accordingly. Nothing in this Agreement shall be construed as effecting an assignment of a right that is not permitted to be made under the terms and the law applicable to such right.

10.3.3 In the event that any counterparty should delay or withhold any consent that is required for the transfer of a Transferred Contract and release of a Seller, with the prior consent of or upon request of the Purchaser 2, the relevant Seller shall terminate such contract as of the earliest possible date. Such termination shall not entail any claims of the Purchaser 2 against the relevant Seller as a result of the termination and the Purchaser 2 hereby releases the relevant Seller from any liability to the Purchaser 2 in such regard, to the extent that the relevant Seller has undertaken all commercially reasonable efforts to obtain such consent.

10.4 Mixed Contracts

In the case of any Mixed Contract, to the extent it is a Transferred Contract, (in particular as regards those contracts transferred by Seller 5):

10.4.1 If the portion of the relevant Mixed Contract that Relates to the Business can be transferred without the consent of, or any payment to, any third party, the relevant Seller shall transfer the portion of such Mixed Contract that Relates to the Business ("Partial Assignment") to the Purchaser 2 at Closing as a Transferred Contract. To the extent that such

24

transfer results in deviating contractual terms (e.g. lower volume discount), the Purchaser 2 shall not be entitled to raise any claims against the relevant Seller.

10.4.2 If the portion of the relevant Mixed Contract that Relates to the Business cannot be transferred in accordance with Section 10.4.1 by the Closing Date, the relevant Seller and the Purchaser 2 shall use their respective best efforts to either

(a) obtain the consent of the applicable third party or parties to a Partial Assignment to the Purchaser 2, effective as of the Closing, on terms reasonably acceptable to the relevant Seller and the Purchaser 2, and to the extent such consent is obtained, the applicable portion of such Mixed Contract shall be assigned to the Purchaser 2 as of the Closing as a Transferred Contract, or

(b) cause the applicable third party or parties to enter into a new agreement with the Purchaser 2, effective as of the Closing (i.e., split the Mixed Contract so that the Purchaser 2 receives its own agreement), on terms reasonably acceptable to the Purchaser 2, pursuant to which the Purchaser 2 shall receive substantially all of the benefits and shall bear substantially all of the costs, liabilities and burdens under the portion of such Mixed Contract that Relates to the Business unless provided otherwise in Section 10.5 which shall apply accordingly.

Neither Party hereto shall be required to pay any consideration or make any material concession in connection with the foregoing.

10.4.3 If such Mixed Contract is not transferable in accordance with Section 10.4.1, and the relevant Seller and the Purchaser 2 can neither obtain the consent of the applicable third party or parties to a Partial Assignment nor cause the applicable third party or parties to enter into a new agreement in accordance with Section 10.4.2, prior to the Closing Date, the relevant Seller and the Purchaser 2 shall use their respective best efforts to enter into a reasonable alternative arrangement (such as a sublease, sublicense or service or operating agreement) with a view to the Purchaser 2 receiving substantially all of the benefits and bearing substantially all of the costs, liabilities and burdens with respect to the applicable portion of such Mixed Contract unless provided otherwise in Section 10.5 which shall apply accordingly. To the extent such alternative arrangement results in material costs to the relevant Seller, Purchaser 2 shall be obliged to compensate 50% of such additional costs evidenced by the relevant Seller.

10.4.4 If a Partial Assignment of a Mixed Contract cannot be effected, Section 10.3.1 as well as Section 10.3.2 shall apply mutatis mutandis. In the event of a dispute between the Parties regarding the allocation of the relevant portions of the Mixed Contract, an independent auditor appointed by the president of the IHK Halle-Dessau shall bindingly decide about the portions. The costs of the arbitrator shall be split equally.

25

10.5 Apportionment

10.5.1 Performance under the Transferred Contracts shall be apportioned with effect to the Closing Date. The relevant Seller shall be responsible for performing any obligations (including payment obligations) under the Transferred Contracts which fall due before the Closing Date and the Purchaser 2 shall be responsible for performing any obligations (including payment obligations) under the Transferred Contracts after the Closing Date. If and to the extent the Purchaser 2 receives payments for goods delivered or services performed on or before the Closing Date under the Transferred Contracts, the Purchaser 2 shall pass on the amounts so received to the relevant Seller within five (5) Business Days from receipt. If and to the extent, after the Closing Date, any Seller receives any invoice for any goods or services under any Transferred Contract relating to the period after the Closing Date, the respective Seller can either pay the invoice directly when due and shall then be compensated by the Purchaser 2 within five (5) Business Days after the relevant Seller has notified the Purchaser 2 in writing about the payment or forward the same to the Purchaser 2 for payment. To the extent that any Seller receives payments for services which are not yet performed or products that have not yet been finalized and packed for transport on the basis of the Transferred Contracts by the Closing Date, the respective Seller shall pass on these amounts to the Purchaser 2. If and to the extent, after the Closing Date, the Purchaser 2 receives any invoice for deliveries or services under any Transferred Contract relating to the period before the Closing Date, the Purchaser 2 can either pay the invoice directly when due and shall then be compensated by the relevant Seller or relevant Affiliate or forward the same to the relevant Seller for payment.

10.5.2 The relevant Seller shall indemnify the Purchaser 2 against all liabilities for which the relevant Seller is responsible pursuant to Section 10.5.1 but subject to the limitations set out in this agreement, in particular Section 25.

10.5.3 The Purchaser 2 shall indemnify the relevant Seller against all liabilities for which the Purchaser 2 is responsible pursuant to Section 10.5.1.

10.5.4 This Section 10.5 shall not apply to any payables and receivables that are sold and transferred under this Agreement and are reflected in the Binding Intangible Working Capital Accounts.

10.6 Purchaser 2 shall be entitled to nominate Purchaser 3 (and Purchaser 3 hereby already consents to such nomination) as transferee of the Transferred Contracts except for the four lease agreements further specified in Schedule 10.1.1(a) instead of Purchaser 2. Purchaser 2 shall exercise the foregoing right by submitting not less than ten (10) Business Days prior to the Closing Date a written declaration to Seller 2 (acting as authorized recipient also for Seller 3) that sets forth the Transferred Contracts which shall be transferred to Purchaser 3. The relevant Transferred Contracts shall be transferred to Purchaser 3 in lieu of Purchaser 2 pursuant to this Section 10. To the

26

extent Purchaser 2 exercises its nomination right under this Section, Purchaser 3 shall be placed in a position as if Purchaser 3 had been the transferee under Section 10.

11. ASSIGNED SITE SERVICES AND SUPPLY AGREEMENT

11.1 Assigned Site Services

Seller 2 shall on or prior to the Closing Date assign and transfer the portion of its rights and obligations relating to the Business and the Schkopau Rubber Facility under the Second Amended and Restated Site Services Agreement entered into by Dow Olefinverbund GmbH and Styron Deutschland GmbH (the legal predecessor of Seller 2) on 1 June 2013 and as set out in Schedule 11.1 ("Assigned Site Services") to the Purchaser 2. Without the prior written consent of Purchaser 2, Seller 2 shall refrain from fully or partially terminating the Second Amended and Restated Site Services Agreement or any services thereof, if and to the extent such termination would impact any of the Assigned Site Services.

The Sellers and the Purchasers assume that the Transaction under this Agreement with respect to the Business triggers a transfer of a part of a business (Betriebsteilübergang) with regard to the employees at the Schkopau Rubber Facility and the sales, customer service and marketing employees in Eschborn.

The Purchaser 2 acknowledges that Schedule 12.1 may be subject to changes due to the Right of Replacement, subject to

27

the Right of Replacement regarding the Key Personnel stipulated in Section 12.6. If any Transferred Employees will not automatically transfer from the Seller 2 and any Affiliate to the Purchaser 2, these employees shall be deemed Individually Transferred Employees within the meaning of Section 12.2. The Sellers and the Purchasers further agree that the Purchaser 1 shall have the right to make an offer of employment to the sales, customer service and marketing employees in Eschborn pursuant to Section 12.2, provided that the Purchaser 1 takes over the accrued pension liabilities with discharging effect for Seller 2 pursuant to Section 4 of the German Pension Act (Betriebsrentengesetz) as of the Closing Date.

The employee relationships of the employees allocated to the Business listed in Schedule 12.2, that will not automatically transfer to the Purchaser 2 in accordance with Section 12.1 ("Individually Transferred Employees"), shall be assumed by or transferred to the Purchaser 1 by offer (Angebot) and acceptance (Annahme) on an individual contractual basis with effect from the Closing Date. The Parties shall use their best endeavours that the employee relationships with the Individually Transferred Employees are assumed by the Purchaser 1 on the basis of the current or in the aggregate comparable terms of employment with effect as from the Closing Date, it being understood that neither the Sellers nor the Purchaser 1 and any Affiliate shall be required to make any payments or grant any other benefits in order to obtain the consent of the Individually Transferred Employees with the transfer of their employment relationship. The Purchaser 1 will offer new employment contracts to Individually Transferred Employees at least five (5) weeks before the Closing Date. The Purchaser 1 acknowledges that Schedule 12.2 may be subject to changes due to the Right of Replacement however, it being understood that such Right of Replacement must not be exercised later than eight (8) weeks before the Closing Date, and except for such employees that are marked as Key Personnel, if any.

Due payments to Transferred Employees whose employment relationships actually transfer to the Purchaser 2 shall be borne among the Parties as follows:

it being understood and agreed by Seller 1 (on behalf of any relevant Affiliate), Seller 2, Seller 3 and the Purchaser 2 that any payments to be made under this indemnification provision shall be calculated on a pro rata basis (based on the number of days elapsed between the beginning of the relevant year and the Closing Date compared to 365 days). It being further understood and agreed by Seller 1 (on behalf of any relevant Affiliate), Seller 2, Seller 3, any relevant Affiliate and the Purchaser 2 that Seller 1 (on behalf of any relevant Affiliate), Seller 2 and Seller 3 shall not be responsible and shall not be required to indemnify the Purchaser 2, respectively, if and to the extent the Purchaser 2 should decide to pay a higher salary, bonus and/or incentive payments to the Transferred Employees and Individually Transferred Employees than required pursuant to existing contractual agreements, applicable laws and regulations as of the Closing Date.

Seller 2 and Seller 3 shall, and Seller 1 shall procure that any relevant Affiliate shall, be responsible, and indemnify the Purchaser 2, for any bonuses payable to the Transferred Employees that are related to the transaction contemplated in this Agreement, and such indemnification shall not be calculated on a pro rata basis. However, as regards retention bonus payments, the Purchaser 2 shall be responsible for such portion that becomes due after the Closing Date.

Seller 2, Seller 3 and Seller 1 confirm that no stock-based compensation of any Transferred Employee will be transferred to the Purchaser 2 or its relevant Affiliate.

12.3.2 The Purchaser 2 shall be responsible, and indemnify the Seller 2, Seller 3 and any relevant Affiliate, respectively, for all salary payments and other claims of each Transferred Employee, provided they do not exercise their right to object to the transfer of their employment, relating to periods starting on or after the Closing Date, including, but not limited to,

It being further understood and agreed by Seller 2, Seller 3, any relevant Affiliate and the Purchaser 2 that the Purchaser 2 shall indemnify Seller 2, Seller 3 and any relevant Affiliate for any claims made by the Transferred Employees against Seller 2, Seller 3 and any relevant Affiliate if and to the extent that the Purchaser 2 has decided to pay a higher salary, bonus and/or incentive payments to the Transferred Employees than required pursuant to existing contractual agreements, applicable laws and regulations as of the Closing Date. As regards any employee inventor remuneration payable to the Transferred Employees, in the relationship between the Parties, only such liabilities are to be borne by the Purchaser 2 that are related to the Sold Intellectual Property Rights, whereas any employee inventor remuneration payable to the Transferred Employees that is unrelated to Sold Intellectual Property Rights is to be borne by Seller 2, Seller 3 and any relevant Affiliate, respectively, and such Seller and its Affiliate, respectively, shall indemnify the Purchaser 2 for all payments for such employee inventor remuneration.

12.3.3 The rights and obligations under this Section 12.3 shall apply accordingly for Individually Transferred Employees, it being understood that the Purchaser 1 shall only be responsible for employment-related liabilities of such Individually Transferred Employees that agree to actually transfer to the Purchaser 1.

12.4 Non-Transferred Employees

The aim of the Parties is to procure that all Transferred Employees accept the transfer. Seller 2 and Seller 3 shall use their best endeavours, and Seller 1 shall procure that any relevant Affiliate shall use its best endeavours, that the number of individuals listed in Schedule 12.1 that object to a transfer of their employment to the Purchaser 2 shall be lower than 10%. As regards employees who are marked as Key Personnel in Schedule 12.1 and Schedule 12.2, Seller 2 and Seller 3 shall use their best endeavours, and Seller 1 shall procure that any relevant Affiliate shall procure its best endeavours, that such employees transfer to the Purchaser 2.

30

If any individual listed in Schedule 12.1 objects to a transfer to the Purchaser 2 ("Non-Transferred Employee"), the following shall apply:

The Sellers and the Purchasers shall promptly inform each other in writing or by written electronic means of any Non-Transferred Employee. The Purchaser 2 shall and Seller 2 and Seller 3 shall, or Seller 1 shall procure that an Affiliate shall, use their respective best efforts to obtain agreement from any Non-Transferred Employee to transfer to the Purchaser 2 within no more than one (1) month after the Closing Date, it being understood that the Purchaser 2, the Seller 2, the Seller 3 and any Affiliate shall not be required to make any payments or grant any other benefits in order to obtain such consent.

If the Non-Transferred Employee holds on to his/her objection to a transfer to the Purchaser 2, the relevant Seller and Affiliate shall terminate the employment relationship with such Non-Transferred Employee within one month to the next feasible date and, unless the relevant Seller is legally obligated to allow that the Non-Transferred Employee provides actual services pursuant to applicable local law or any court order,  put the Non-Transferred Employee on irrevocable garden leave (unwiderrufliche Freistellung). The relevant Seller and Affiliate on the one hand and the Purchaser 2 on the other hand share the actually occurring costs for the winding-up of the employment relationship with the Non-Transferred Employee (i.e. the remuneration for the Non-Transferred Employee until the termination date including the employer’s contributions to the social security schemes, any compensation for untaken holidays and any severance payments) on a USD-for-USD basis in a ratio of 50:50, however, with the Purchaser 2 not bearing more than USD 243,000 for each of the Non-Transferred Employees, including for the avoidance of doubt any taxes and social security contributions. For the time periods during which a Non-Transferred Employee provides actual services to the relevant Seller and Affiliate, respectively, the remuneration for such time period shall be fully borne by the relevant Seller and Affiliate, respectively, unless the relevant Seller is legally obligated to allow that the Non-Transferred Employee provides actual services pursuant to applicable local law or any court order.

12.5 Excluded Employees

Seller 2 will retain employees, who are based at Seller 2's facility in Schkopau and do not perform functions that are relevant to the Business on a standalone basis ("Excluded Employees"). Although by operation of German employment law, the Excluded Employees would transfer automatically to the Purchaser 2, the Sellers will use their best endeavours to retain them by splitting the retained business and Excluded Employees from the Business in good time before the Closing Date. The Purchaser 2 acknowledges that the group of Excluded Employees may be subject to changes due to the Right of Replacement and the consultations with the works council on the allocation of the employees pursuant to Section 12.9. The Purchaser 2 shall have no obligation whatsoever to make any payments or grant any other benefits in order to obtain the consent of an Excluded Employee with the continuation of its employment relationship with Seller 2.

31

12.6 Key Personnel

Irrespective of any existing retention agreements and to the extent legally permissible, the Sellers and the Purchasers shall take reasonable steps to encourage employees marked as 'Key Personnel' in Schedule 12.1 and Schedule 12.2 ("Key Personnel") to remain with the Business. Where, nevertheless, individual members of the Key Personnel exceptionally leave the Business, the Sellers shall provide a reasoned proposal to replace the person and – subject to the prior written consent of Purchaser 2 (i.e. email or signed letter), not to be unreasonably withheld, – replace this person by another similar employee that will be deemed a Transferred Employee or Individually Transferred Employee depending on applicable local law, whereby it is understood that the Right of Replacement does not apply to the Key Personnel.

12.7 Required Functions

The Sellers and the Purchasers share the understanding that additional persons need to be employed in order to operate the Business in a stand-alone mode as of the Closing Date or as soon as practicable thereafter. Schedule 12.7 contains a list of functions and the assumed salary level for such functions ("Required Functions"). As part of the Migration Project (Section 20.2), Seller 2 shall use its best endeavors to support the Purchaser 2 with identifying the required personnel to fill the Required Functions.

12.8 German Non-Tariff Employees

Transferred Employees and Individually Transferred Employees that are employed in Germany and that receive an annual base salary exceeding the highest wage group in the applicable collective bargaining agreements are German non-tariff employees (außertarifliche Angestellte) ("German Non-Tariff Employees"). The Seller 2 and Seller 3 shall, and Seller 1 shall procure that any relevant Affiliate shall, be responsible, and indemnify the Purchaser 2, for any increase in such conditions that is agreed between the Signing Date and the Closing Date. For the avoidance of doubt, this shall not apply if (i) any increase of such conditions is required under existing collective or individual agreements, (ii) concerns any regular increase of remuneration or (iii) is resulting from a promotion.

12.9 Reconcilement of interest agreement and social plan

The Purchaser 2 is aware and acknowledges that Seller 2 will negotiate with its works councils (Betriebsräte) on a reconcilement of interests agreement (Interessenausgleich) ("ROI") and social plan (Sozialplan) ("SP") governing the transfer (Versetzungen) of Excluded Employees to the remaining business and the split of the business operation in Schkopau to allocate the Excluded Employees to the remaining business or Business. The conclusion of the ROI and the SP require the prior information of the Purchaser 2 to the extent they contain obligations for the Purchaser 2, including, inter alia, redundancy restrictions, severance payments and other benefits which are beyond the protection and benefits agreed in Section 12.10.

The Parties agree that the provisions governing the restricted actions between Signing and Closing pursuant to Section 20.4.2 do not apply to the conclusion of the ROI and SP as well as to the fulfillment of any obligation under the ROI and SP between Signing and Closing. The Purchaser 2 shall procure that the ROI and SP will be maintained if

32

the Purchaser 2 transfers the Business or parts thereof or any Transferred Employees or Individually Transferred Employees to any other legal entity before the expiry of the ROI and SP after the Closing Date to the extent required such continuation would arise from mandatory law.

12.10 Protection of Transferred Employees and Individually Transferred Employees in Germany.

The Sellers and the Purchaser 2 agree as a contract to the benefit of the Transferred Employees (Vertrag zugunsten Dritter) that for a period of twenty-four (24) months after the Closing Date, the Purchaser 2 and its Affiliates undertake not to

12.10.1terminate the employment of the Transferred Employees for operational reasons (betriebsbedingte Kündigungen),

12.10.2change the work location of the Transferred Employees to an area that is not in within a radius of fifty (50) kilometres of the work location of such Transferred Employee immediately prior to the transfer, and

12.10.3change the employment terms and conditions to the detriment of the Transferred Employees, it being understood that this does not include a workplace guarantee,

unless, in each case, to the extent legally permissible under local law, mutually agreed between the Purchaser 2 and the affected Transferred Employees or their representatives. The Purchaser 2 will procure that the protection of Transferred Employees will be maintained if the Purchaser 2 transfers the Business or parts thereof or any Transferred Employees to any other legal entity before the expiry of the twenty-four (24) months-period after the Closing Date. Subject to the Purchaser 2 reimbursing the Sellers and any of their Affiliates for any severance pay or similar compensation costs including, but not limited to, any remuneration, bonus, benefits, statutory and/or contractual pension and social security contributions until and including the last day of employment with the Sellers or the relevant Affiliate, this Section 12.10 shall not apply to Transferred Employees who are not employed by Seller 2 in Germany.

The Purchaser 2 will, or will procure that its relevant Affiliate will, agree as a contract to the benefit of the Transferred Employees (Vertrag zugunsten Dritter), to join the employers' association of the chemical industry (Arbeitgeberverband Nordostchemie e.V.) which concludes collective bargaining agreements with the trade union IG BCE and to maintain membership for a period of at least twenty-four (24) months after the Closing Date.

The rights and obligations under this Section 12.10 shall apply accordingly for the Purchaser 1 with respect to the Individually Transferred Employees except for the obligation to join the employers' association of the chemical industry (Arbeitgeberverband Nordostchemie e.V.). The Sellers and the Purchaser 1 agree as a contract to the benefit of the Individually Transferred Employees (Vertrag zugunsten Dritter) that the Purchaser 1 will apply the collective bargaining agreements to the Individually Transferred Employees, provided they are no German Non-Tariff Employees, as if the Purchaser 1 were a member of the employers' association for a period of at least twenty-four (24) months after the Closing Date.

The Purchaser 2 shall, and shall cause its Affiliates to, indemnify and hold harmless the Seller 2, and each of its representatives from all costs, damages or other financial disadvantages arising from Purchaser 2 or its Affiliates' failure to reasonably cooperate with the Seller 2 or any of its representatives to inform any employee representatives.

To the extent that the Parties fail to reach an agreement on the Tangible Transfer Inventory, each Party shall have the right to refer the matter to another auditing firm to be agreed between the Parties (the "Expert"). The Expert shall be instructed to determine, within thirty (30) Business Days of referral, the items still in dispute by way of a binding written expert opinion pursuant to sections 317 et seq. BGB mutatis mutandis. The costs of the Expert shall be borne pursuant to the principles set forth in sections 91 et seq. German Civil Procedure Code (Zivilprozessordnung). The results determined by the Expert shall become binding upon delivery of the expert opinion to the Parties. The Tangible Transfer Inventory resulting from this procedure is referred to as the "Binding Tangible Transfer Inventory".

If the Parties do not reach agreement on the appointment of another auditing firm within five (5) Business Days following Closing or if the chosen auditing firm refuses to accept the instruction, the auditing firm to be instructed to prepare the Tangible Transfer Inventory and the Intangible Working Capital Accounts as per the Closing Date shall be chosen by the Institute of Certified Public Accountants (Institut der Wirtschaftsprüfer) in Düsseldorf on terms reasonably acceptable to such auditing firm upon written request of either Party.

14.2 The instructed audit firm shall send the Intangible Working Capital Accounts to the Parties within six (6) weeks after the Closing Date. To the extent that the Parties agree on the Intangible Working Capital Accounts within one (1) week after receipt of the Intangible Working Capital Accounts, the Intangible Working Capital Accounts become binding. To the extent that the Parties fail to reach an agreement on the Intangible Working Capital Accounts, each Party shall have the right to refer the matter to the Expert pursuant to the mechanism set out in Section 14.1 which shall apply mutatis mutandis. The results determined by the Expert shall become binding upon delivery of the expert opinion to the Parties. The Intangible Working Capital Accounts

39

resulting from this procedure are referred to as the "Binding Intangible Working Capital Accounts".

14.3 If the volume of the net working capital in relation to the Sold Tangible Assets shown in the Binding Tangible Transfer Inventory exceeds a normalised volume of 37.75 kilotons or amounts to less than 37.75 kilotons, then the Purchase Price pursuant to Section 13 increases or is reduced by one (1) per kiloton of difference from the normalised volume of 37.75 kilotons multiplied by the latest available market price per kiloton at the time of Closing, as the case may be (the "Tangible WC Balance Amount"). In case of an increase of the Purchase Price, the Purchasers shall pay to the Sellers the Tangible WC Balance Amount within one (1) week after the Tangible Transfer Inventory has become binding in its entirety pursuant to Section 14.1. In case of a reduction of the Purchase Price, the Sellers shall – and the Sellers shall settle internally accordingly – pay to the Buyer the Tangible WC Balance Amount within one (1) week after the Tangible Transfer Inventory has become binding in its entirety pursuant to Section 14.1. In both cases, interest shall be paid on the Tangible WC Balance Amount as of the Closing Date at a rate of two (2) percentage points above the basis interest rate pursuant to section 247 BGB applicable at the time p.a.

14.4 If the value of the net working capital in relation to the Intangible Working Capital Accounts shown in the Binding Intangible Working Capital Accounts prepared as per the day immediately prior to the Closing Date, 24:00 hrs exceeds an amount of USD 47 million or amounts to less than USD 47 million, then the Purchase Price pursuant to Section 13 increases or is reduced by the amount of the difference as the case may be (the "Intangible WC Balance Amount"). In case of an increase of the Purchase Price due to the Binding Intangible Working Capital Accounts exceeding an amount of USD 47 million, the Purchasers shall pay to the Sellers the Intangible WC Balance Amount within one (1) week after the Intangible Working Capital Accounts has become binding in its entirety pursuant to Section 14.2. In case of a reduction of the Purchase Price due to the Binding Intangible Working Capital Accounts amounting to less than an amount of USD 47 million, the Sellers shall – and the Sellers shall settle internally accordingly – pay to the Purchasers the Intangible WC Balance Amount within one (1) week after the Intangible Working Capital Accounts has become binding in its entirety pursuant to Section 14.2. In both cases, interest shall be paid on the Intangible WC Balance Amount as of the Closing Date at a rate of two (2) percentage points above the basis interest rate pursuant to section 247 BGB applicable at the time p.a.

15. VAT AND OTHER TAXES

15.1 German VAT

The Parties agree the following with regard to German VAT ("VAT-G"):

15.1.1 The Parties are of the view that transactions, deliveries and services agreed and performed under this agreement by Seller 2, in particular the sale and transfer of the Business respectively the Seller 2 Business and hence the Sold Assets (including the Rubber Hereditary Building Right) respectively the Seller 2 Sold Assets constitute a transfer of a going concern (Geschäftsveräußerung im Ganzen) within the meaning of section 1 para 1a UStG and therefore, should not be subject to VAT-G. Notwithstanding any deviating decision of the Tax authorities (in which

40

case in particular Sections 15.1.5 through 15.1.7 shall apply), the Parties agree to (i) treat the sale and transfer of the Seller 2 Sold Assets accordingly as a transfer of a going concern and (ii) inform the Tax authorities about their view and treatment in due course after the Closing Date (either separately or in the process of the regular VAT-G filings including monthly advance self-assessments).

15.1.2 Seller 2 declares that it is an entrepreneur (Unternehmer) within the meaning of section 2 UStG and that the sale and transfer of the Seller 2 Business and hence the Seller 2 Sold Assets respectively are part of its business activities. The Purchasers warrant that they each are an entrepreneur (Unternehmer) within the meaning of section 2 UStG and that the Business (including the Seller 2 Business) and hence the Sold Assets (including the Seller 2 Sold Assets) are being purchased as part of its business activities; the Purchasers warrant to continue the Business (including the Seller 2 Business) with the Sold Assets (including the Seller 2 Sold Assets).

15.1.3 In the past, Seller 2 has reclaimed from the Tax authorities any VAT-G charged for goods or services that were procured and intended for use by Seller 2's businesses as input VAT-G, and Seller 2 will continue to do so for the period up to the Closing Date. The Purchasers are aware that input VAT-G adjustment periods applicable to Seller 2 are in progress, will extend beyond the Closing Date and will be assumed and continued by the Purchasers in case of a transfer of a going concern, i.e. the Purchasers will take over the input VAT-G correction items and remaining adjustment periods pursuant to section 15a UStG applicable to Seller 2. Should the Tax authorities issue any notice amending the tax assessment as regards the input VAT-G deducted by Seller 2 under section 15a UStG in relation to the Seller 2 Sold Assets due to facts and circumstances prevailing prior to the Closing Date and should the Tax authorities hold the Purchasers liable in this regard, Seller 2 shall be obliged, between Seller 2 and the Purchasers (inter se), to indemnify the Purchasers against any input VAT-G correction amounts that may have to be paid to the Tax authorities. A respective payment claim shall be due and payable in accordance with Section 15.6.4 below. If and to the extent that any input VAT-G relating to periods prior to the Closing Date relating to the Seller 2 Sold Assets and, therefore, to the Seller 2 Business as well as any supplies or services received in relation thereto has not or not fully been claimed, but is subject to an adjustment relating to a VAT-G correction occurring after the Closing Date for the benefit of the Purchasers according to section 15a UStG, such correction claim shall be made for the account of Seller 2 and the Purchasers shall pay such positive input VAT-G correction amounts to Seller 2, unless such adjustment was triggered by the Purchasers due to a change of circumstances relevant for the input VAT-G treatment after the Closing Date.

15.1.4 Seller 2 agrees to provide the Purchasers with any information and documentation required for the implementation of an actual correction

41

of input VAT-G related to the Seller 2 Sold Assets and to submit the requisite information and documentation to the Purchasers according to section 15a para 10 UStG within two (2) months after the Closing Date.

15.1.5 As a precautionary measure (precautionary option for VAT-G in accordance with section 9.1 para 3 sentence 3 VAT-G Application Decree (Umsatzsteueranwendungserlass)), Seller 2 hereby waives the VAT-G exemption pursuant to section 4 no. 9 lit. a UStG and opts, pursuant to section 9 para 1 in conjunction with para 2 and 3 UStG, for VAT-G in relation to the sale and transfer of the Rubber Hereditary Building Right. Section 15.1.7 shall apply accordingly.

15.1.6 The Purchase Price (including the Rubber Hereditary Building Right Purchase Price) specified in this Agreement does not include VAT-G. If the sale and transfer of the Business and hence the Sold Assets or parts of it (e.g. for the Seller 2 Sold Assets) does not constitute a transfer of a going concern within the meaning of section 1 para 1a UStG, the sale and transfer of the Seller 2 Sold Assets or – if and to the extent sold, delivered or deemed delivered in Germany – any other Sold Assets forming part of the Transaction is subject to VAT; the Purchase Price to be paid to the Sellers in particular to Seller 2 shall be increased by statutory VAT (and any other comparable Tax in any other applicable jurisdiction) that may apply except where the relevant VAT would already be owed by the Purchasers under the reverse charge mechanism according to section 13b para 5 and para 2 no 3 UStG (e.g. in relation to the Rubber Hereditary Building Right) in which case such VAT shall be paid and settled by the Purchasers to the Tax authorities directly. If and to the extent any additional charges (e.g. the statutory interest in accordance with section 233a AO) will be assessed and charged to any Seller (including Seller 2), the Purchasers shall indemnify the relevant Seller (in particular Seller 2) for any amount of such charges.

15.1.7 In case and to the extent of a VAT able transaction, the Sellers agree to provide the Purchasers with due and proper invoices pursuant to sections 14 and 14a UStG, mentioning, to the extent applicable, the Purchasers’ liability to pay VAT (reverse-charge). Any VAT shown in the invoice of the relevant Seller to the Purchasers shall be due for payment no earlier than ten (10) Business Days after submission of the invoice. This Agreement does not constitute an invoice for VAT purposes.

15.1.8 The Purchasers indemnify the Sellers against ancillary charges, including interest, resulting from a treatment of the sale and transfer of the Business and/or the Sold Assets as a transaction subject to VAT.

15.1.9 The Parties are not required to submit or support any appeal against an appealable ruling or decision by the tax authorities that the sale and transfer made hereunder does in whole or in part not constitute a sale and transfer of a business as a whole.

42

15.2 Belgian VAT

The Parties agree the following with regard to Belgian VAT:

15.2.1 The Parties consider that Belgian VAT should, in principle, not be applicable on the transactions contemplated by Seller 4 in this Agreement due to:

(a) a sale of Seller 4's shares in TRS being exempt from Belgian VAT in accordance with the provisions of article 44, §4, 10° of the Belgian VAT Code; and

(b) the transfer of the Transferred Contracts by Seller 4 to a non-Belgian Purchaser that qualifies as a VAT taxable person (i.e. a B2B transaction) being considered to take place for VAT purposes in the jurisdiction in which the relevant Purchaser is established in accordance with the provisions of article 21, §2 of the Belgian VAT Code; or

(c) the transfer of the Transferred Contracts by Seller 4 to a Belgian Purchaser that qualifies as a VAT taxable person (i.e. a B2B transaction) or to a Belgian or non-Belgian Purchaser that does not qualify as a VAT taxable person (i.e. a B2C transaction), being considered to take place for VAT purposes in Belgium in accordance with the provisions of article 21, §2 and 21bis of the Belgian VAT Code, and the fair market value of the Transferred Contracts being USD 0; or

(d) the transfer by Seller 4 of the shares in TRS together with the Transferred Contracts being exempt from Belgian VAT in accordance with the provisions of article 11 and 18, §3 of the Belgian VAT Code due to being considered as a sale and transfer of a business as a whole in going concern.

15.2.2 The Purchase Price or any other consideration paid or payable to Seller 4 in respect of a transfer specified in this Agreement does not include Belgian VAT. If the sale and transfer of the Seller 4 Sold Assets or – if and to the extent sold, delivered or deemed delivered in Belgium – any other Sold Assets forming part of the Transaction is subject to Belgian VAT, the Purchase Price to be paid to the Sellers, and in particular to Seller 4 shall be increased by statutory Belgian VAT that may apply except where the relevant VAT would already be owed by the Purchasers under the reverse charge mechanism in which case such VAT shall be paid and settled by the Purchasers to the Tax authorities directly.

15.2.3 In case and to the extent of a Belgian VAT taxable transaction, the Sellers agree to provide the Purchasers with due and proper invoices, mentioning, to the extent applicable, the Purchasers’ liability to pay VAT (reverse-charge). Any VAT shown in the invoice of the relevant Seller to the Purchasers shall be due for payment no earlier than ten (10) Business Days after submission of the invoice. This Agreement does not constitute an invoice for Belgian VAT purposes.

43

15.2.4 The Purchasers indemnify the Sellers against VAT and additional charges, including interest, resulting from a treatment of the sale and transfer of the Sold Assets as a transaction subject to Belgian VAT. If and to the extent any additional charges (e.g. interest, fines, increases, etc.) will be assessed and charged to any Seller (including Seller 4), the Purchasers shall indemnify the relevant Seller (in particular Seller 4) for any amount of such charges.

15.3 Swiss VAT

15.3.1 Seller 3, Seller 5 and the Purchaser 1 shall use their best efforts to ensure that the notification procedure pursuant to art. 38 of the Swiss VAT law applies to the transfer of the Business pursuant to this Agreement. At the time of the conclusion of this Agreement, the Swiss VAT number of Seller 3 is CHE-223.013.167 MWST and the Swiss VAT number of Seller 5 is CHE-114.496.932 MWST.

15.3.2 At Closing, Seller 3, Seller 5 and the Purchaser 1 shall complete all documents to be submitted under the Swiss VAT notification procedure. After execution of this Agreement, the Seller 3 and Seller 5 are obliged to duly and timely submit these documents to the Swiss Federal Tax Administration ("SFTA") and to provide the Purchaser 1 a copy of the submitted documents. The Seller 3 and Seller 5 are not obliged to provide the Purchaser 1 with documents or records of use (i.e. the Swiss VAT history and VAT treatment) of the subject matter of purchase or copies of invoices, paid or claimed Swiss input VAT in connection with the purchase object, calculations of Swiss input VAT adjustments or Swiss input VAT depreciations or similar documents and information.

15.3.3 If, notwithstanding such efforts mentioned above, any VAT is payable on the transfer of the Business or any part thereof under this Agreement, the relevant Seller shall, upon request, provide the relevant Purchaser with a Swiss VAT compliant invoice and the relevant Purchaser shall pay to the relevant Seller the VAT due in addition to the Purchase Price, i.e. the Purchase Price is to be understood as exclusive of any VAT. Any VAT which may be payable as a result of a change in the relevant Swiss input VAT recovery rate in respect of the subject matter of purchase shall be borne by the relevant Purchaser.

15.4 German Operational Taxes etc.

15.4.1 The Notary advised the Parties on section 75 AO, under which a purchaser taking over a business as a going concern is liable for any German operational taxes or German withholding taxes triggered by any act or occurrence in the period between the beginning of the calendar year prior to the takeover and the takeover itself. In the event that claims for Seller 2's Taxes are brought against the Purchasers by the Tax authorities under section 75 AO in relation to the Seller 2 Sold Assets and/or the Seller 2 Business, as the case may be, Seller 2 agrees to indemnify the Purchasers against any such Tax liabilities originally owed by Seller 2.

44

15.4.2 The Seller 2 further undertakes to indemnify the Purchasers with respect to any taxes under section 11 para 2 and section 12 German Real Estate Tax Act (Grundsteuergesetz, GrStG) related to the Original Hereditary Building Right and/or the Rubber Hereditary Building Right for the period up to the Closing Date, insofar as the Purchasers are held liable for such Taxes owed by Seller 2.

15.5 Swiss Operation Taxes

15.5.1 Seller 3 and Seller 5 hereby undertake to fully compensate and indemnify Purchasers for and against any secondary liability for all Swiss Taxes and Swiss Social Security Contributions primarily owed by Seller 3 and Seller 5 relating to any time period, or part of a time period, up to and including Closing or any event which occurred on or before Closing, to the extent such Taxes and Swiss Social Security Contributions have not been paid or are not accrued or provided for in the Closing Statement and deducted from the Purchase Price, including any secondary liability of the Purchasers (if any at all) in relation to

(a) any liability for Swiss Taxes and Swiss Social Security Contributions arising out of any act, omission, event or transaction occurring during any period up to and including the Closing Date;

(b) any liability for, or reduction of entitlement to refunds and credits of, Swiss Taxes and Swiss Social Security Contributions arising by reference to, as applicable, capital, equity, income, profits or gains earned, accrued or received during any period up to and including the Closing Date; and

15.6 Miscellaneous

15.6.1 In the event that Taxes are claimed from the Purchasers by the Tax authorities and the Sellers have to indemnify the Purchasers for such Taxes, the Sellers agree to provide the Purchasers upon request with all Tax-related information relating to such Tax the Purchasers may require to build a defence against the Tax authorities. The Purchasers shall be required to raise and/or file any remedies (in particular appeals (Einspruch)) or make and/or file any applications (e.g. payment deferral (Aussetzung der Vollziehung)) against the respective tax assessment notice (Steuerbescheid oder Steuerfestsetzung) or liability assessment notice (Haftungsbescheid) if requested to do so by a Seller or if timely instructions cannot be obtained from the Sellers. The Purchasers shall conduct the defence in relation to such Tax or liability notices as lawfully instructed by the relevant Seller and in good faith and using all reasonable means and defences available to it. The Purchasers shall keep the Sellers timely informed of the development of any such Tax proceedings. The Purchasers shall not settle or compromise any such

45

Tax proceeding or Tax claim without the prior written consent of the Sellers which shall not be unreasonably withheld, conditioned or delayed. Sellers’ consent shall be deemed if they do not submit their written comments within twelve (12) Business Days after having been informed by the Purchasers in writing about the intent to settle a tax proceeding. If the Purchasers fail to comply with their obligations, an indemnification by the Seller shall be excluded.

15.6.2 Any external costs reasonably incurred by the Purchasers in relation to tax proceedings and its defence as requested by the Seller in accordance with this Section 15.6, shall be borne by the Sellers, provided prior to the Purchasers’ engagement of an external advisor the Sellers have been consulted and granted their approval in writing.

25. REMEDIES AND CLAIMS

25.1 Purchaser Claim

If a Sellers' Warranty is entirely or partially not correct or the Sellers have breached any other obligation under this Agreement (thereby giving rise to a "Purchaser Claim"), the Purchasers shall, subject to the limitations and exclusions set forth in this Agreement, be entitled to request the Sellers to put Purchasers within forty (40) Business Days into the same position that they would have been in if the Sellers’ Warranty had been correct or had not been breached (Naturalrestitution), or, at the election of Purchasers, to pay damages for non-performance (so-called "kleiner" Schadenersatz statt der Leistung) to the Purchasers. The Purchasers undertake to raise any Purchaser Claim (including, for the avoidance of doubt, any Purchaser Claim which may be based on more than one legal ground but also on a violation of any of the Sellers' Warranties) covered under the W&I Insurance only against the insurer under the W&I Insurance policy (as defined below) and in no event against the Sellers.

25.2 Indemnifiable Losses

25.2.1 The liability of the Sellers under this Agreement for breaches of Sellers’ Warranties shall be determined on the basis of all liabilities, reasonable costs and expenses and other damages within the meaning of sections 249 et seqq. BGB incurred by the Purchasers, (i) including any restitution costs (Herstellungskosten), and (ii) typically foreseeable consequential or indirect damages (typischerweise vorhersehbare mittelbare Schäden), including damages caused by interruptions of the Business (Betriebsunterbrechungsschäden), but excluding (x) any lost profits (entgangener Gewinn), (y) any other indirect damages (mittelbare Schäden) or consequential damages (Folgeschäden) and (z) internal costs, it being understood that all relevant losses and damages referred to in this Section shall be calculated on a USD-for-USD basis.

25.2.2 Losses shall be reduced by all benefits (including avoided losses, actual Tax benefits and savings, and increases in the value of any asset (Abzug neu für alt)) of the Purchasers that are recovered by the Purchasers or any of their Affiliates, as the case may be, in connection with the relevant matter.

25.2.3 Losses shall be reduced by the amount of the relevant claim that is

(a) recovered by a Purchaser from a third party, and

(b) covered by an insurance of a Purchaser or any of a Purchaser's Affiliates, or would have been covered by an insurance if the insurance cover of the Sellers existing at Closing had been continued in the same scope as prior to Closing.

25.2.4 Losses shall be disregarded to the extent they result from, or are increased by, (i) the passing of any new law or any change in any law, rule, regulation or interpretation of any law by competent courts or any

69

change in any administrative practice of any government, governmental department, agency or regulatory body after the Closing Date that applies to the Business or a Purchaser, (ii) any act, to which a Purchaser has expressly declared its consent; (iii) any change made after the Closing Date in any accounting or taxation policies or practice of a Purchaser unless such change was made by a Purchaser due to applicable mandatory law.

25.2.5 The principles of mitigation of damages (section 254 BGB) shall apply; each Purchaser is in particular obliged to prevent the occurrence of any damages and to limit the scope of any damages incurred. The Purchasers shall not, except as required under applicable law, make, or invite authorities or other third parties to make any audits, investigations, explanatory measures, notifications or other acts that could be expected to lead to a claim for a breach of a Seller's Warranty or under an indemnification obligation against a Seller under this Agreement unless any such action is required to (i) limit or reduce the risk of higher damages in future or (ii) eliminate any actual risk which could cause damages to the Purchasers, their employees or the public within the meaning and scope of section 254 BGB.

25.3 Third Party Claims

25.3.1 In the event that (i) a claim against a Purchaser is asserted, made or threatened by a third party (including any public authority including, but not limited to, social security authority, but excluding Tax authorities) or (ii) an audit or investigation is being or will be conducted by any court or public authority (including, but not limited to, social security authority), which, in each case, may give rise to a Purchaser Claim ("Third Party Claim"), the following shall apply:

(a) If a Purchaser becomes aware of any Third Party Claim, the relevant Purchaser shall:

(i) without undue delay, but in any event within twenty (20) Business Days of becoming so aware, give notice of such Third Party Claim to the Sellers, specifying in reasonable detail the legal basis and the amount of such Third Party Claim, and consult with the Sellers in respect of such Third Party Claim;

(ii) allow the Sellers to participate in any scheduled negotiations or proceedings relating to any Third Party Claim to the extent there are no legitimate business reasons of the relevant Purchaser that prevent the Sellers to participate;

(iii) without prejudice to the relevant Purchaser's obligations pursuant to section 254 para 2 BGB, take all reasonable steps as the Sellers may request to mitigate, avoid, contest, remedy or defend such Third Party Claim and any adjudication in respect of such Third Party Claim or to enforce against any person (other than the Sellers) the rights of the relevant Purchaser in relation

70

to the subject matter of the Third Party Claim subject to the receipt of an adequate advance payment by Sellers covering the costs for any such requested action as reasonably calculated by the relevant Purchaser;

(iv) during normal business hours and upon advance notice, allow the Sellers and their accountants and professional advisers to inspect and take copies of all books, correspondence and records of the Business necessary for the defence and relating to the Third Party Claim unless there are no legitimate business reasons of the relevant Purchaser that prevent such inspection and if such inspection is granted, only to the extent persons inspecting such records enter into confidentiality agreements;

(v) fully cooperate with the Sellers in relation to the defence of any Third Party Claim with reasonable efforts; and

(vi) except with the Sellers' prior consent, not admit liability in respect of or compromise, or settle any Third Party Claim.

If (i) the Sellers cannot agree on common instructions or do not give instructions at all or (ii) no advance payment is received from the Sellers by the relevant Purchaser, each within the deadline set by the relevant Purchaser, the relevant Purchaser may decide on the further procedure at its own discretion and without prejudice regarding the Sellers’ obligations within this Section 25.3.

(b) Within two (2) weeks of receipt of the notice pursuant to Section 25.3.1(a)(i), the Sellers are entitled to assume control of the defence against any Third Party Claim by giving notice to the relevant Purchaser to the extent legally permitted. The Sellers shall be entitled to take any action they deem necessary to defend, appeal, compromise or settle the Third Party Claim (including the assertion and pursuit of counter-claims or the claims against any third parties) in the name and on behalf of the relevant Purchaser provided that (i) any such action complies with the strategy agreed with the relevant Purchaser and (ii) no such action violates any valid interest of the relevant Purchaser. The assumption of control of the defence against any Third Party Claim shall not be construed to constitute an acknowledgement of liability by the Sellers with respect to such Third Party Claim. If the Sellers decide not to assume control of the defence against a specific Third Party Claim, the relevant Purchaser shall have control of such defence and may contest such Third Party Claim, provided that the relevant Purchaser complies at all times with its obligations pursuant to Section 25.3.1. In this case, the Sellers shall use reasonable efforts to support the relevant Purchaser's actions (e.g. by providing any information related to the Third Party Claim).

(c) The costs and expenses incurred in relation to the defence against any Third Party Claim shall be borne as follows:

71

(i) All costs and expenses reasonably incurred by the relevant Purchaser (other than internal costs such as labour or overhead costs) shall, to the extent the Third Party Claim constitutes a claim for which, subject to the limitations set forth in this Agreement, the Sellers are liable, be borne by the Sellers, subject to the relevant Purchaser having complied with its obligations under this Section 25.3.1.

(ii) All costs and expenses reasonably incurred by the Sellers (other than internal costs such as labour or overhead costs) shall, to the extent the Third Party Claim does not constitute a claim for which, subject to the limitations set forth in this Agreement, the Sellers are liable, be borne by the relevant Purchaser, subject to (i) the Sellers having complied with their obligations under this Section 25.3.1. If and to the extent the afore-mentioned requirements are fulfilled, the Sellers shall be entitled to a refund of their advance payment pursuant to Section 25.3.1 (a) (iii).

(iii) In respect of all other costs and expenses incurred by the Sellers or the relevant Purchaser, each Party shall bear its own costs and expenses.

(d) If and to the extent a Third Party Claim is acknowledged by way of a final or enforceable court judgment, or arbitral award (rechtskräftiges Urteil oder Schiedsspruch) or a binding settlement agreement entered into by the relevant Purchaser after having obtained the Sellers' consent, the Sellers shall indemnify and hold the relevant Purchaser harmless from and against any acknowledged Third Party Claim upon first request.

25.3.2 The provisions of this Section 25.3 shall not apply

(a) to the extent that the Third Party Claim may reasonably be expected to result in a claim covered by the W&I Insurance policy (and not against the Sellers), which shall be made exclusively through implementation of the W&I Insurance Policy; and

(b) to Tax proceedings vis-à-vis Tax authorities.

25.4 Exclusion of Claims

25.4.1 The Sellers shall not be liable to the Purchasers for any breach of the Sellers' Warranties or the other obligations under this Agreement nor shall the Purchasers be entitled to bring any claim under this Agreement if and to the extent that:

(a) the Purchasers or any Affiliate of the Purchasers have participated in causing (mitverursacht) such claim or has failed to comply with its duty to mitigate damages (section 254 BGB);

(b) the Sellers have indemnified the Purchasers for the losses caused by such breach;

72

(c) the disadvantages to be compensated are taken into consideration in the Binding Tangible Transfer Inventory and/or Binding Intangible Working Capital Accounts, leading to a reduction of the Purchase Price within the framework of the adjustment of the Purchase Price according to Section 14;

25.4.2 The Sellers shall not be liable to the Purchasers for any breach of the Sellers' Warranties nor shall the Purchasers be entitled to bring any claim for breaches of the Sellers' Warranties if and to the extent that the facts and circumstances underlying the relevant breach were actually known (positive Kenntnis) by Zbigniew Warmuz, Laurent Guillermin, Wieslaw Ziembla, Michal Nowak and Lukasz Dopart, provided that such individuals shall be deemed to have actual knowledge of all matters which were

(a) disclosed in this Agreement, including its Schedules; or

(b) fairly disclosed in the documents and the written answers provided in the electronic data room operated by Datasite accessible through the website https://www.datasite.com/us/en.html until 20 May 2021 ("Data Room"). Matters are fairly disclosed in the Data Room if they are disclosed in a manner that is not misleading and in such detail that it could reasonably be concluded from the information disclosed in the Data Room that a claim or a liability exists. One electronic copy of the Data Room stored on a USB-Stick is deposited by the Parties on the Signing Date, immediately following the execution of this Agreement, with the officiating notary for evidentiary purposes. The officiating notary did not check the contents of the USB-Stick delivered to him. The notary is hereby instructed

−to keep the USB-Stick in safe custody until 31 December 2024;

− to provide each Party upon its written request with a hard or soft copy of all or a specified part of the data stored on the USB-Stick whereas after provision of the requested copy the original USB-Stick shall be put back in the envelope and the envelope shall be re-sealed;

−not to hand out the original USB-Stick to any of the Parties;

− to destroy the USB-Stick after expiry of the deposit period whereas the Parties waive a destruction log being recorded.

The notary accepts this instruction as an ancillary supporting service within the meaning of sec. 24 German Notary Code. The notary advised that the USB-Stick will be stored in a dry and dark place, however, that he does not accept any liability as regards the durability and legibility of the stored data nor has he taken any special measures or taken out insurance protection against burglary, theft, fire, water or natural hazards to which the persons appearing agreed to.

73

(c) disclosed to the Purchasers, any of its or their directors, employees or agents or any of its or their advisers or other representatives at any of the Expert Sessions; or

(d) publicly available (e.g. in respective publicly accessible registers) or are otherwise in the public domain.

25.5 Limitation Periods

25.5.1 All claims of the Purchasers against the Sellers under and in connection with this Agreement shall be time-barred (verjähren) eighteen (18) months after the Closing Date, except for claims of the Purchasers (i) for a breach of a Seller's Warranties pursuant to Sections 23.1 (Corporate Existence), 23.2 (Authority) and 23.3 (Ownership of Sold Assets) and (ii) under Section 27 (Environmental Indemnity) which shall in each case be time-barred three (3) years after the Closing Date.

25.5.2 The expiry period for the claims of the Purchasers as specified in Section 25.5.1 shall be suspended (gehemmt) and the time of suspension shall not be included in the calculation of the limitation period pursuant to section 209 BGB, if the Purchasers give notice to the Sellers of such claim before the expiry of the time limitation specified in Section 25.5.1. Such suspension of the expiry period shall, however, be fully disregarded with retroactive effect (i.e. time passed during the effectiveness of the suspension is also taken into account for the calculation of the limitation period) if the Purchasers fail to initiate arbitral proceedings in accordance with Section 34.3 within six (6) months after the Sellers have been notified. Section 203 BGB shall not apply.

25.6 De Minimis and Threshold

The Sellers shall only be liable for a breach of a Sellers' Warranty if and to the extent (i) the amount of such claim brought by the Purchasers exceeds the amount of USD 50,000 (in words: United States Dollar fifty thousand) ("De Minimis") and (ii) the aggregate amount of all individual claims exceeding the De Minimis (i.e. only to such extent as exceeds the De Minimis) exceeds an aggregate amount of USD 500,000 (in words: United States Dollar five hundred thousand) ("Threshold"). If the aggregate amount of all individual claims exceeding the De Minimis exceeds the Threshold, the Purchasers shall be entitled to claim the entire amount of such claims (Freigrenze) (for the avoidance of doubt: except for claims below the De Minimis which can in no event be claimed). Losses arising out of the same event or related events shall count as a single claim for the purpose of the De Minimis Claim and Threshold amounts in this Section 25.6.

25.7 Cap

25.7.1 Except as set out in Sections 25.7.2 and 25.7.3, the total liability of the Sellers for breaches of the Seller's Warranties shall be limited to an aggregate amount of USD 1 (in words: United States Dollar one).

74

25.7.2 The Sellers' aggregate liability for all claims for breaches of the Sellers' Warranties under Sections 23.1 (Corporate Existence), 23.2 (Authority) and 23.3 (Ownership of Sold Assets) stemming solely from facts and circumstances that have arisen after the Signing Date and are specified in the bring down declaration pursuant to Section 21.2.1, shall be limited to the Purchase Price.

For the purpose of this Section, claims of the Purchasers shall be deemed not or only partially covered under the W&I Insurance if and to the extent that (i) the relevant claim as such is not insured under the W&I Insurance or (ii) the W&I Insurance does not provide coverage due to the disclosures in the bring down declaration pursuant to Section 21.2.1.

Prior to Signing, the Purchasers have informed the Sellers about the current status of the negotiations with the insurer. The current draft of the terms and conditions of the insurance policy as provided to the Purchasers is for documentation purposes contained in Schedule 25.8. The Purchasers shall use their best efforts to take out a W&I Insurance pursuant to market terms and with the best warranty coverage reasonably available and to provide the Sellers with an executed version of such W&I Insurance no later than seven (7) Business Days following the Signing Date. Upon request, the Sellers shall cooperate in good faith with the Purchasers to support the Purchasers in taking out the W&I Insurance (e.g. by providing information reasonably required in connection with the W&I Insurance and by enabling the W&I Insurer to conduct a due diligence within the same scope as the Purchasers’ due diligence for the purposes of the W&I Insurance).

25.8.2 The Purchasers shall pay the premium and other amounts payable under the W&I Insurance policy as set forth therein and, promptly upon request, provide proof of such payments to the Sellers.

25.8.3 The Purchasers undertake, during the term of the W&I Insurance policy

75

25.8.4 to maintain the W&I Insurance policy in full force and effect;

25.8.5 not to agree to amend the W&I Insurance policy without the Sellers' prior approval; and

25.8.6 not to assign the W&I Insurance policy without the Sellers' prior approval.

25.8.7 The Purchasers confirm and represent to the Sellers that no claim of the Purchasers against the Sellers under, or in connection with, this Agreement is assigned or subrogated to the insurer under the W&I Insurance policy and that the W&I Insurance policy shall expressly exclude any such assignment or subrogation except in cases of willful deceit (arglistige Täuschung) or intentional behavior (Absicht oder Vorsatz) of the Sellers.

25.8.8 There shall be no liability of the Sellers for Purchaser Claims based on the violation of any of the Sellers' Warranties (including, for the avoidance of doubt, any Purchaser Claim which may be based on more than one legal ground but also on a violation of any of the Sellers' Warranties) under this Agreement to the extent that a Purchaser has a valid claim against the W&I Insurance, but the insurer under the W&I Insurance policy has denied to provide payment under the W&I Insurance policy for any of such Purchaser Claims for any reason whatsoever.

25.8.9 The validity and collectability risk in respect of the W&I Insurance policy shall solely and irrevocably rest with the Purchasers and shall have no impact on the exclusion or limitations of liability provided for in this Agreement for any Purchaser Claim.

25.9 Exclusive Remedy

25.9.1 The Parties agree that the remedies that the Purchasers may have against the Sellers for breach of this Agreement are solely governed by this Section 25, and the remedies provided for by this Section 25 shall be the exclusive remedies available to the Purchasers, unless specifically set forth in this Agreement.

25.9.2 Apart from the rights of the Purchasers under this Section 25, the following rights and claims of the Purchasers are hereby expressly excluded and waived (verzichtet):

(a) except of the rights under Section 26, any right to (i) withdraw (zurücktreten) from this Agreement or (ii) to require the winding-up of the transactions contemplated under this Agreement (e.g. by way of so-called "großer" Schadenersatz or Schadenersatz statt der ganzen Leistung, damages instead of entire performance);

76

(b) any claims for breach of pre-contractual obligations (Verschulden bei Vertragsverhandlungen), including but not limited to claims arising under sections 241 para. 2, 311 paras 2, 3 BGB;

(c) any claims for breach of ancillary obligations (Nebenpflichten), including but not limited to claims for damages arising under sections 241 para 2, 280 BGB;

(e) all remedies of the Purchasers for defects of the purchase object including but not limited to claims arising under sections 437 through 441 BGB.

25.10 Wilful Misconduct

28.1.2 The Purchasers may withdraw (zurücktreten) from this Agreement prior to Closing if (i) not all of the Closing Conditions have been satisfied until the expiry of the Long-Stop Date; or (ii) the Sellers have failed to completely perform all Closing Actions to be performed by them pursuant to Section 21.2 within five (5) Business Days following the Scheduled Closing Date and upon lapse of a sufficient deadline to cure such defect set out in written notice from the Purchasers to the Sellers, unless the Purchasers are responsible for (haben zu vertreten) the non-fulfilment of the relevant Closing Condition or Closing Action. For the avoidance of doubt, the Purchasers shall in no event be responsible for the non-fulfilment of the Closing Conditions pursuant to Sections 19.1.1(b), 19.1.1(c), 19.1.1(d) and 19.1.1(e). In the event of a non-fulfilment of the Closing Condition pursuant to Section 19.1.1(a), the Purchasers shall only be entitled to withdraw from this Agreement if despite the Purchasers having complied with their obligations under this Agreement the Competent Merger Control Authorities have finally and definitely refused to grant the required Merger Control Clearances (and in particular confirmed that there are no conditions and/or requirements available that would allow the Merger Control Clearances to be granted).

28.1.3 A withdrawal pursuant to Section 28 is only valid if the Purchasers have received a notice of withdrawal (Rücktrittserklärung) in writing, and, with respect to the termination rights set forth in Sections 28.1.1(i) and 28.1.2, and if, by the time of such receipt, the Closing Conditions have not yet been completely satisfied.

28.2 Legal consequences of withdrawal

83

USD 50,000,000 (in words: United States Dollar fifty million) ("Break Fee"), which shall be secured by a Bank Guarantee. Conversely, in the event of a withdrawal of the Purchasers from this Agreement pursuant to Section 28.1.2 due to the Sellers not having fulfilled their obligations under Section 19.1.1(b) or due to the Sellers not having made reasonable best efforts to achieve a fulfilment of the Closing Condition pursuant to 19.1.1(d) or the Closing Condition pursuant to Section 19.1.1(b) not being satisfied or, despite a written notice by the Purchasers and a cure period of ten (10) Business Days having lapsed not fulfilling a Closing Action owed by them, the Sellers shall pay to the Purchaser 1, a break fee in the amount of USD 50,000,000 (in words: United States Dollar fifty million) as liquidated damages (pauschalierter Schadensersatz).

28.2.3 This Section 28, Sections 30 through 34 (inclusive) shall survive any withdrawal, without limit in time.

28.2.4 For the avoidance of doubt, notwithstanding any right to withdraw from this Agreement as set out in this Section, the Party's right to claim fulfilment of this Agreement shall remain unaffected as long as the right to withdraw is not validly exercised.

32. ASSIGNMENT

Claims and other rights out of or in connection with this Agreement can only be transferred with the prior consent of the respective other Party/Parties. To the extent that the transfer cannot be excluded validly, the Parties are obligated not to transfer the respective right without the prior consent of the respective other Party/Parties. This shall not apply to the granting of securities/collaterals within the acquisition financing of the Purchasers in relation to the Transaction.

33. COSTS

All notary, court, registration or similar fees, real estate and other transfer Taxes (including any real estate transfer Tax in connection with the sale and transfer of the (or parts of the) Original Hereditary Building Right and/or creation, the sale and transfer of the Rubber Hereditary Building Right, but excluding VAT, that is dealt with in Section 15.1), stamp duties and other public levies, as well as the costs or fees of any filings connected with the execution and implementation of this Agreement, shall be borne by the Purchasers. Any Swiss securities transfer Taxes, if any, shall be borne by the party to which it is imposed under applicable laws. Save as aforesaid, each Party shall bear its own costs and Taxes and the costs of its advisors.

34. FINAL PROVISIONS

34.1 This Agreement contains the entire agreement reached between the Parties on the subject of this Agreement. There are no side agreements. The officiating notary advised the persons appearing that all contractual provisions must be completely and duly notarized. Any provision of an agreement which is not notarized is null and void and may cause the invalidity of the whole agreement.

34.2 Amendments and supplements to this Agreement as well as the waiver of any rights under this Agreement shall be in written form (excluding, however, transmission by way of telecommunications) in order to be valid unless a stricter form is required. This also applies to any amendment to, or cancellation of, this written form clause.

34.3 All disputes between the Parties arising out of or in connection with this Agreement or regarding its validity are finally decided by an arbitration tribunal comprising three (3) arbitrators in accordance with the Arbitration Rules of the German Institution for Arbitration (Deutsche Institution für Schiedsgerichtsbarkeit e.V.) as amended from

88

time to time without recourse to the ordinary courts. The chairman of the arbitration panel must have the qualification required to be admitted to the German bar and all arbitrators must be fluent in English. The place for arbitration proceedings is Frankfurt am Main, Germany. The language for arbitration proceedings is English; documents in the German language do not need to be translated into the English language.

34.4 The place of exclusive jurisdiction for all judicial acts relating to arbitration proceedings in accordance with section 1062 para 1 nos 1 to 4 Civil Procedure Code (Zivilprozessordnung) is Frankfurt am Main, Germany.

34.5 This Agreement is governed by German law. Any possible current or future obligations between the Parties which fall under the EC Regulation No 864/2007 on the Law Applicable to Non-Contractual Obligations ("Rome II") are also governed by German law.

34.6 Should a provision of this Agreement be or become null and void as a whole or in part, or should a gap in this Agreement become evident, this shall not affect the validity of the remaining provisions. In such case, such valid and practicable regulation shall be agreed that in legal and economic terms comes closest to what the Parties intended or would have intended in accordance with the purpose of this Agreement if they had considered the point at the time of entering into this Agreement. If the nullity of a provision is due to a degree of performance or time (period or deadline) laid down in this provision, then the provision shall be agreed with a legally permissible degree that comes closest to the original degree. It is the express intention of the Parties that this severability clause shall not merely reverse the burden of proof but that section 139 BGB is contracted out as a whole, which means that this Agreement is upheld despite there being a void provision or a gap. However, in derogation of the preceding provisions, this Agreement shall be null and void as a whole if it is null and void in relation to individual parties or if an essential contractual provision is null and void and the partial nullity would change the overall nature of the Agreement.
